Q: Airport Utility on iMac (Late 2012) after El Capitan Update

About a week after the May 17th El Capitan Update on my iMac, I opened Airport Utility and saw Updates for my Time Capsule and two Airport Extremes were available and thus, clicked on and completed them.  A few days later when I opened Airport Utility on my iMac, all three devices appeared with Warning Triangles that they were no longer seen.  So, I Removed them and assumed Airport Utility would see them after powering them down and back up.  BUT, Airport Utility doesn't see anything except my Internet Connection.  I read to download the iOS version of Airport Utility which I did and can see on my iPhone that everything appear as it had been (Internet to Time Capsule and the two Airport Expresses off that).  So, just curious IF my problem is similar to others and IF an El Capitan and or Airport Utility "fix" is forthcoming?  I'm asking as Time Machine won't work given it can't see the Time Capsule.  Thank You.

iMac (21.5-inch, Late 2012), OS X El Capitan (10.11.5)

Hi,

 

"I'm asking as Time Machine won't work given it can't see the Time Capsule."

 

 

Shut down your Mac

 

Unplug your internet cable modem from the electrical outlet

 

Wait 10 seconds then plug the internet cable modem back into the the electrical outlet

 

Unplug the Time Capsule and both AirPort Extremes from the electrical outlet

 

Wait ten seconds then plug the Time Capsule and Airport Extremes back in to the electrical outlet

 

Wait 30 seconds then turn your Mac back on

    Airport Utility on the iMac still shows Internet only.  The Time Capsule and two Airport Express are not seen nor discoverable.  I do see everything on my iPhone (iOS App of Airport Utility),

    Hi,

     

    You may need to, "reset" both the Time Capsule and Airport Extremes.

    OK.  I'll try that later and report back.  For now, just seems odd that everything works fine and is visible via iOS Airport Utility ... but not on the desktop iMac.  Wasn't an Issue to me until Time Machine popped up to report it no longer sees the Time Capsule.
